ABSTRACT:
Provided are thermosetting powder coating compositions which contain a quaternary ammonium salt or hydroxide having at least one substituent of eight carbons or more and one lower alkyl group. Such quaternary ammonium salts or hydroxides were found to catalyze the curing or cross-linking reaction at lower temperatures in such compositions than previously possible.
